Answer:

BC ≈ 5.87

Step-by-step explanation:

The law of sines is applicable.

a/sin(A) = 7/sin(50°)

Angle A is the complement of angle B, so we have ...

a = 7(sin(40°)/sin(50°))

a ≈ 5.8736974

The length of BC is about 5.87 units.

NEED THE ANSWER ASAP! Find the measure of the missing angle X

jasenka [17]

Answer:

50°

In order to determine the unknown angle, be sure to use the total sum of 180° 

120° - 180°= 60° ( this give you the red side inside the triangle)

Then you simple add the two number inside the triangle

60° + 70° = 130°( then you use this to find the missing corner by subtracting from 180°)

180°- 130° = 50° this is your missing angle X"

To prove it simple add all the 3 angles inside the triangle add up to 180°

60° + 70° + 50° = 180°

X = 50°
